Daily, ritualized prayer in and of itself is a wonderful meditation. Just ask Hassids and Qabbalists world-wide!
There are two methods of meditation I employ on a need-based schedule. The first is designed for separating my ka from my body. Through this method, I hope to walk the Necropolis freely when I will. It's also the method I use when being tutored by Wepwawet. The second method I've lifted from fiction in true chaote fashion. It's simply the "flame and the void" meditation from Robert Jordan's WoT series. I use this one for thaumaturgic work (IMG:
